TECHNICAL FIELD

The present invention relates to an electronic test apparatus and a function menu display method used therefor, and more particularly to an electronic testing apparatus having a function menu for listing plural pages arranging plural menu items on one screen, to be used in instruction of execution of various functions for processing test data of objects displayed on a screen, and a function menu display method therefor.

BACKGROUND ART

Generally, in a test data display system used in electronic test apparatuses such as communication characteristic testing apparatus, a display section for displaying tested data of objects on a screen is provided in an operation panel, and plural function keys for execution of a plurality of functions for processing the test data of objects are also provided in the operation panel.

In such a test data display system, a function menu arranging plural menu items corresponding to plural function keys are displayed on the screen of the display section.

The user refers to a menu item displayed as a function menu on the screen of the display section, and presses the function key corresponding to the menu item of the function desired to be executed, so that the execution of the function is instructed to the electronic test apparatus.

In such an electronic test apparatus, usually, the function menu corresponding to each function is displayed on the screen.

Therefore, to execute a certain function, the screen must be changed over to the one corresponding to a desired function, and the function menu is changed over by pressing the function key corresponding to the desired function.

Recently, as the data processing and display system used in electronic testing apparatuses can handle multiple functions, multiple function menus are needed.

Therefore, these function menus can be displayed on the screen of the display section only by pressing the function keys provided in the operation panel, and the function menus corresponding to one screen are prepared in plural pages or in plural layers.

Thus, in the data processing and display system used in multifunctional electronic test apparatus, since the number of pages or layers of function menus is increased, it is hard for the user to instantly select a desired function on the screen of the display section.

For example, if the user forgets some of the function menus, when a certain function is executed, the user must change over the pages or layers of the function menus on the screen of the display section, and search for the function menu with the desired menu item.

Accordingly, in the data processing used in the electronic testing apparatus or test data display system, the operational efficiency is lowered despite the multi-function ability.

For example, as the function key 20, seven keys from F1 to F7 are provided.

Therefore, in the function menu area in the display screen 19 a, a function menu arranging seven menu items corresponding to the seven function keys 20 is displayed (however, it is not always required that menu items corresponding to all function keys 20 should be provided in the function menu).

The page change key 22 is a key used for changing over the pages of the function menu displayed at the right side of the display screen 19 a of the display unit 19.

As mentioned above, only seven menu items corresponding to the seven function keys 20 can be arranged in the function menu.

Therefore, when eight or more menu items are present, a function menu for plural pages is prepared.

When a function menu for plural pages is prepared, by pressing the page change key 22 as mentioned above, the function menu pages can be sequentially changed over.

The list display key 24 is a key used for instructing a list display of function menus.

The detail of the function menu list window displayed when the list display key 24 is pressed is explained later.

The screen change key 26 is a key used for instructing changeover of display content displayed on the display screen 19 a of the display unit 19.

The electronic test apparatus has a plurality of screens corresponding to the functions, and the display state of the screen 19 a is changed over sequentially by operation of the screen change key 26.

The focus key 27 is for instructing changeover of windows to be used among plural windows displayed on the display screen 19 a of the display unit 19.

That is, the display screen 19 a of the display unit 19 comprises windows corresponding to specific functions. When the focus key 27 is pressed, the windows to be operated are changed over sequentially, so that the user can execute a desired function.

The set key 41 is a key for setting the moving position of the cursor or the like.

The encoder 29 is an operating member for moving the cursor or numerical value of a parameter by rotation, and instructing input or decision of selection of parameters when pressed.

The function menu data 13 a of the function menu displayed in the display screen 19 a of the display unit 19 by the screen manager 10 a is explained below by referring to FIGS. 3A and 3B.

The electronic test apparatus has a plurality of screens (Screens 1, 2, 3, . . . ) depending on the functions, as shown in FIG. 3A.

Each one of Screens 1, 2, 3, . . . comprises plural windows corresponding to specific functions (in the example in FIG. 3A, Windows 1, 2, 3 for Screen 1).

By operation of the screen change key 26, when a certain screen is displayed, plural windows prepared on this screen can be sequentially turned to active windows by operation of the focus key 27.

In each window, the function data of function menu displayed when the window becomes active is prepared in correspondence to each other.

In the example shown in FIG. 3A, for instance, in window 1, function menu data including menu items F1 to F14 (function menu data of two pages) is prepared.

In window 2, function menu data including menu items F1 to F7 (function menu data of one page) is prepared.

In window 3, function menu data including menu items F1 to F21 (function menu data of three pages) is prepared.

Therefore, while a certain screen 1 is being displayed, when execution of list display of function menu is executed by the list display key 24, a function menu list is prepared and displayed, concerning the function menu data prepared respectively for windows 1, 2, 3 by the function menu list display section 10 a 1.

The electronic test apparatus further incorporates function menu data corresponding to hard keys (1, 2, . . . ) 31, 32, . . . for inputting execution instructions of display of function menu corresponding to specific functions.

For example, relating to the hard key (1) 31 a, it shows data of function menu including menu items F1 to F14 (function menu data of two pages) is prepared.

Relating to the hard key (1) 31 a, it shows data of function menu including menu items F1 to F21 (function menu data of three pages) is prepared.

Therefore, in a operated state of any one of the hard keys 31 a, 31 b, . . . , when execution of list display of function menu is instructed by the list display key 24, the function menu list is compiled and displayed, concerning the function menu data corresponding to a specific hard key to be displayed by the function menu list display section 10 a 1.

FIGS. 4A and 4B show an outline of the function menu area provided in the display screen 19 a of the display unit 19 and the function menu list window to be displayed by pressing of the list display key 24.

As shown in FIG. 4A, a function menu area is provided at the right side of the display screen.

The screen manager 10 a displays the function menu by the display control section 18 so that each menu item of the function menu may be positioned corresponding to the key position of the function key 20 provided next to the right side of the display screen 19 a on the operation panel of the panel unit 14.

When the user presses the list display key 24, the function menu list display section 10 a 1 compiles a function menu list by using the function menu data 13 a of the function menu of each window on the screen being presently displayed, and displays in the function menu list window of the display screen 19 a as shown in FIG. 4B.

Herein, the size of the function menu list window to be displayed on the display screen 19 a can be freely set.

In the example shown in FIG. 4B, the function menu list window displays a list of function menu composed of three pages, but the function menu of other number of pages may be similarly displayed in list.

Further, since multiple function menus are prepared for the screen (window) to be displayed, if a list of function menus of one page cannot be displayed completely due to inadequate display screen size, a plurality of function menu lists can be compiled.

In this case, if the instruction for changing over the display of the function menu list windows is made through the input control section 16, the page manager 10 a sequentially changes over the function menu lists in the function menu list window according to the instruction.

If a function menu corresponding to a specific function is displayed in the function menu area by pressing a specific hard key, when the list display key 24 is pressed by the user, the function menu list display section 10 a 1 creates a function menu list by using the function menu data 13 a of the function menu corresponding to the specific function being presently displayed, and similarly displays in the function menu list window.

Specific examples of lists display of function menu corresponding to operation on the list display key 24 provided in the panel unit 14 are explained while referring to FIGS. 5A, 5B, 5C and 5D.

FIGS. 5A, 5B, 5C and 5D show the relation of a certain screen 1, plural windows 1 to n included in the screen 1, function menus provided in the windows 1 to n, and function menu lists displayed when the list display key 24 is pressed while the screen 1 is being displayed.

That is, the screen 1 shown in FIG. 5A includes a display result display window (window 1), parameter setting window (window 2), and report result display window (window n) as shown in FIG. 5B.

Supposing the test result window is active, herein, as shown in FIG. 5C, of the menu items F1 to F14 prepared as the function menu to be displayed in window 1, F1 to F7 are displayed as the function menu of a first page, and F8 to F14 as function menu of a second page, as shown in FIG. 5D.

Similarly, when the parameter-setting window of window 2 is active, menu items F1 to F7 prepared as the function menu to be displayed in widow 2 are arranged and displayed as function menus of one page as shown in FIG. 5D.

When the report result display window of window n is active, menu items of F1 to F21, that is, menu items of F1 to F7, F8 to F14, and F15 to F21 are arranged and displayed as function menu of one page as shown in FIG. 5D.

Herein, function menus F8 to F14 corresponding to window 1, F1 to F7 of window 2, and F15 to F21 of window n are common menu items of the same contents.

When the list display key 24 is pressed, the function menu list display section 10 a 1 compiles a function menu list corresponding to each window by using the function menu data 13 a corresponding to the screen 1 to be displayed presently, and a function menu list window is provided, and the list is displayed in this window.

The function menu list display section 10 a 1 unifies the function menu items common in each window when compiling the function menu list, so that the same menu item may not be duplicated in the function menu list.

In the function menu area, only the function menu of the presently active window is displayed, but in the function menu list displayed by instruction on the list display key 24, whether active or inactive, the function menus corresponding to all windows included in the screen to be display are displayed in a list.

FIGS. 6A, 6B, 6C and 6D show specific examples of the display screen 19 a before and after display of the function menu list window 32.

First, FIG. 6A shows a specific example of the display screen 19 a when the hard key 31 b is operated for inputting the execution instruction of display of function menu corresponding to a specific function in the panel unit 14 shown in FIG. 2.

In this case, at the right side in the display screen 19 a, the function menu 30 of the first page is displayed, and it is shown that the function menu data of three pages, 1, 2, 3, is prepared in the lowest area.

The screen 19 a of the present display includes a test result display window 34 and a parameter setting window 36.

In this case, since the test result display window 34 is an active window, the function menu 30 includes the menu item corresponding to the test result display window 34.

FIG. 6B shows a specific example of the display screen 19 a when the list display key 24 is pressed in the state in FIG. 6A.

In FIG. 6B, the function menu list window 32 is displayed in partly overlapped state with the test result display window 34 and parameter setting window 36.

In this case, the test result display window 34 and parameter setting window 36 are displayed only in part due to limitation of the size of display screen, but usually, when active (the state in FIG. 6A), by scrolling by using the cursor key 28 or the like, all data displayed in the window can be checked.

Tags are set in the function menu 30 and function menu list window 32.

The tag indicates a major item summing up parameters and display items shown in the screen and window.

In the test result display window 34 in FIGS. 6A and 6B, “Power Test,” “Frequency Error,” and “Occupied Bandwidth” are tags.

That is, as shown in FIG. 6A, during display of the test result display window 34 and parameter setting window 36, when execution of list display of function menu is instructed by the list display key 24, the function menu list display section 10 a 1 sets the function menu list window 32 as shown in FIG. 6B. Thus, the function menu list including the function menu corresponding to the test result display window 34 and parameter setting window 36 is displayed.

In this case, function menus of three pages are displayed in list in the function menu list window 32.

In each lower part of the function menus of three pages displayed in the list in the function menu list window 32, columns of pages 1, 2, 3 are provided, and the page indicated by shading is the page of the corresponding function menu.

FIG. 6C shows a specific example of the display screen 19 a in which the cursor 41 is movably set in order to select a menu item, in the function menu list window 32.

That is, in the displayed state of the function menu list window 32, when the cursor key 28 or encoder 29 is operated, the function menu list display section 10 a 1 moves the cursor 41 in each menu item of the function menu list window 32 accordingly.

As a result, the cursor 41 is moved to the position of the menu item desired by the user, and when determination of selection is displayed by pressing the set key 40 or encoder 29, the screen manager 10 a changes over the display of window corresponding to the selected menu item.

In each function menu, as shown in FIGS. 6A to 6C, the “TAG” indication is added to the menu item corresponding to the tag provided in the window.

When the menu item indicated by the “TAG” is selected, the screen manager 10 a displays a specific display region in the screen corresponding to the selected menu item, that is, the corresponding tag in the window including the specified menu item, at the beginning of the window, and also displays by adding a specific display attribute (for example, highlighting) to show that the function can be executed (that is, an active tag).

For example, when the menu item (Occupied Bandwidth) in the function menu list window 32 is selected, the display range is changed so that the tag “Occupied Bandwidth” in the test result display window 34 may be displayed at the beginning position of the window (position of “Power Test” in FIGS. 6A to C), so that the detail following the tag is displayed without requiring scrolling of the test result display window 34.

FIG. 6D shows a specific example of the display screen 19 a in the case of execution by searching out the menu item required by operating the set key 41 or pressing the encoder 29 as “Block Error Rate” in a column of the second page in the function menu list window 32 is selected by the cursor key 41 in FIG. 6C.

Thus, when the user only manipulates the list display key 24, whether active or inactive, a list of function menus corresponding to each window is displayed, and all function menus assigned in the screen can be easily checked, and a desired menu item can be searched and selected, and executed.

Therefore, when utilizing functions corresponding to plural windows alternately, for example, when repeating the operation of setting of parameters in the parameter setting window 36 and checking of the result of execution of test by the setting on the test result display window 34, the user does not have to make complicated operations of changing over the active windows and displaying necessary tags, by manipulating the page change key 22, focus key 27, cursor key 28, or encoder 29.

In this case, only by displaying the function menu list window 32 by manipulating the list display window 24 and selecting a desired menu item from the window 32, if the desired window is inactive, the portion of the corresponding tag in the pertinent window can be displayed.

That is, if there are multiple functions and multiple function menus are prepared, the user has only to operate the list display key 24, thus the operation is much simplified and the handling efficiency is enhanced.

The technique described in this embodiment may be used as the program to be executed by a computer, and can be presented to various devices by writing into various memory media, for example, magnetic disk (flexible disk, hard disk, etc.), optical disk (CD-ROM, DVD, etc.), or semiconductor memory.

The program can be also presented to devices by transferring through communication media.

The computer for realizing this apparatus reads in the program recorded in the recording media, or receives the program through communication media, and executes the process as the operation is controlled by the program.

Thus, the electronic test apparatus of the invention can easily execute a desired function by selecting from the function menus even when function menus corresponding to multiple functions are provided.

As described herein, according to the invention, only by manipulating the list display key, it has a function of list display of a function menu composed of plural pages arranging plural menu items on one screen used in instruction of execution of mutually different plural functions for processing tested data of objects displayed on a screen.
